Download or read book Manual Asymmetries Handedness and Motor Performance written by Pamela Bryden and published by Frontiers Media SA. This book was released on 2016-06-10 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: The performance of most tasks with one hand, typically the right, is a uniquely human characteristic. Not only do people prefer to use one hand rather than the other, but also they usually perform tasks faster and more accurately with this hand. The study of manual asymmetries and what such performance differences between the two hands reveal about brain organization and motor function has been a topic of considerable research over the last several decades. The aim of this Research Topic is to review and further explore the origins of manual asymmetries and their relationship to handedness, unimanual and bimanual motor performance, and brain function. The articles included here involve original research conducted in humans or non-human models species, as well as theoretical perspectives, review articles, and meta-analyses.

Download or read book Handedness and Brain Asymmetry written by Marian Annett and published by Psychology Press. This book was released on 2013-04-15 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brain asymmetry for speech is moderately related to handedness but what are the rules? Are symmetries for hand and brain associated with characteristics such as intelligence, motor skill, spatial reasoning or skill at sports? In this follow up to the influential Left, Right Hand and Brain (1985) Marian Annett draws on a working lifetime of research to help provide answers to crucial questions. Central to her argument is the Right Shift Theory - her original and innovative contribution to the field that seeks to explain the relationships between left-and right-handedness and left-and right-brain specialisation. The theory proposes that handedness in humans and our non-human primate relations depends on chance but that chance is weighted towards right-handedness in most people by an agent of right-hemisphere disadvantage. It argues for the existence of a single gene for right shift (RS+) that evolved in humans to aid the growth of speech in the left hemisphere of the brain. The Right Shift Theory has possible implications for a wide range of questions about human abilities and disabilities, including verbal and non verbal intelligence, educational progress and dyslexia, spatial reasoning, sporting skills and mental illness. It continues to be at the cutting edge of research, solving problems and generating new avenues of investigation - most recently the surprising idea that a mutant RS+ gene might be involved in the causes of schizophrenia and autism. Handedness and Brain Asymmetry will make fascinating reading for students and researchers in psychology and neurology, educationalists, and anyone with a keen interest in why people have different talents and weaknesses.
Download or read book Hemispheric Specialisation in Animals and Humans written by Joël Fagot and published by Psychology Press. This book was released on 1997 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Functional cerebral specialization is a phenomenon of considerable relevance not only to those investigating normal brain function, but also to scientists who study and treat clinical populations. This special issue of "Laterality" brings together contributions from researchers studying human populations and those using animal models, and includes a discussion of the important issues in the field of lateralization of function. The papers address the origins of laterality and the nature of lateralized functions in various species, as well as relations among the different forms of lateralization. Included are such topics as lateralized memory processes, early experiential effects on laterality, the genetic basis of handedness, perceptual processing in the haptic or visual domain, and learning. Comparisons between human and non-human primate findings and the implications of these findings for our understanding of the phylogenetic basis of hemispheric specialization are also emphasized.; The papers are based on presentations at two symposia that took place in August 1996: "Issues in Laterality", held at the International Congress of Psychology in Montreal; and "Laterality and Hemispheric Specialization in Primates: Brain Behavior and Evolution", held at the University of Wisconsin, Madison, at the joint meetings of the "XVI Congress of the International Primatological Society" and the "XIX Conference of the American Society of Primatologists".

Download or read book Manual Skills Handedness and the Organization of Language in the Brain written by Gregory Króliczak and published by Frontiers Media SA. This book was released on 2019-08-15 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whereas the cerebral specialization for skilled manual actions (praxis) seems closely linked to dominance for language, with both functions left lateralized in the vast majority of humans, the neural correlates of hand preference are still less well understood. Indeed, as a combination of inherited and non-inherited genomic factors (i.e., direct parental and concealed environmental contributions), handedness – in contrast to language – is less likely to have strong genetic indices and clearly lateralized functional organization. What about eye dominance, unimanual and bimanual object manipulation, and gestures, or attentional systems and the related egocentric or allocentric coding of space? Are these different categories functionally and structurally interconnected? Is their development and contribution to task performance linked, even if they are differently lateralized? How are they connected to language learning or its development? In trying to understand these relationships and their neural underpinnings we obtain a new insight into fundamental human behaviors, which depend either on shared or distinct cerebral resources that must, nevertheless, be harmonized by higher-order cerebral processing. In this Research Topic we assembled a dozen of original research contributions, as well as articles with more theoretically-driven perspectives, that directly speak to these issues. Hopefully this work will serve as a foundation for further discussions and will stimulate new research in this fascinating domain.

This book was released on 2007-05-08 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: `Rather than being an esoteric aspect of brain function, lateralization is a fundamental characteristic of the vertebrate brain essential to a broad range of neural and behavioral processes.' Professor Lesley J. Rogers, Chapter 1 of Side Bias: A Neuropsychological Perspective. This volume contains 14 chapters from a veritable `United Nations' of experts in the field of lateralization of function. They write comprehensive reviews, present data, and pose new questions concerning the evolutionary origins and development of side bias, methodological concerns with the way we measure handedness and footedness, and some more unusual aspects of human beings' lateralized behavior, such as asymmetrical cradling and pseudoneglect. The book will be essential reading for students of behavioral neuroscience and neuropsychology interested in lateralization of function as well as for established researchers in the field.

Download or read book Lateralization and cognitive systems written by Sebastian Ocklenburg and published by Frontiers Media SA. This book was released on 2015-02-24 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Left-right asymmetries of structure and function are a common organization principle in the brains of humans and non-human vertebrates alike. While there are inherently asymmetric systems such as the human language system or the song system of songbirds, the impact of structural or functional asymmetries on perception, cognition and behavior is not necessarily limited to these systems. For example, performance in experimental paradigms that assess executive functions such as inhibition, planning or action monitoring is influenced by information processing in the bottom-up channel. Depending on the type of stimuli used, one hemisphere can be more efficient in processing than the other and these functional cerebral asymmetries have been shown to modulate the efficacy of executive functions via the bottom-up channel. We only begin to understand the complex neuronal mechanisms underlying this interaction between hemispheric asymmetries and cognitive systems. Therefore, it is the aim of this Research Topics to further elucidate how structural or functional hemispheric asymmetries modulate perception, cognition and behavior in the broadest sense.
Download or read book Beyond Left and Right Handedness written by Elke Kraus and published by Springer Nature. This book was released on 2023-08-16 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Handedness is a multidimensional phenomenon co-determined by polygenetic and developmental aspects, multifactorial influences and in some cases, pathological impact. It is important for professionals working with children, including those who are still undecided about their writing hand, to assess, analyse and understand the complexity of handedness comprehensively to prevent problems related to switched or atypical handedness. Beyond Left and Right Handedness uses a practice-based approach to handedness and systematically integrates theory, research and practice. Part I, ‘Theory and Research,’ critically evaluates and utilises the broad spectrum of the handedness literature as a theoretical basis for the development of handedness instruments. Part II, ‘Assessment and Analysis,’ presents diagnostic and analytical instruments developed by the author based on numerous in-depth studies and extensive clinical practice over 20 years. These include the Handedness Profile, a standardised assessment of various handedness dimensions; and the Handedness Typology, an analytical framework to interpret different types of handedness. Part III, ‘Implications for Practice,’ contains detailed case studies on assessment and treatment by professionals working with children presenting with unclear and/or atypical handedness. “This book provides the reader with a comprehensive and scholarly discussion of the topic, presenting a careful, in-depth description of all aspects of the topic and providing professionals with the necessary, evidence-based tools to address handedness in practice. It is an invaluable resource that is well situated in the latest evidence-based understanding of handedness and provides a comprehensive guide to addressing the important development of handedness.” - Prof. Dr. Helen Polatajko

Download or read book Laterality written by Clare Porac and published by Academic Press. This book was released on 2015-12-22 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Left-handedness has been connected to many different conditions, traits, and abilities. This is especially true for pathological syndromes, such as schizophrenia, along with learning disabilities and autism. The published research on handedness is vast and frequently contradictory, often raising more questions than providing answers. Questions such as: Is handedness genetic? Can handedness be changed? Are there consequences to training someone to switch handedness? Are there positive traits associated with left-handedness like creativity? Are there negative traits associated with left-handedness like trouble reading maps? Is it abnormal to do some things right-handed and other things left-handed? Are the brains of left-handers different from the brains of right-handers? Laterality: Exploring the Enigma of Left-Handedness examines the research conducted over the past 50 years with special emphasis on twenty-first century research on handedness and translates this literature into an accessible and readable form. Each chapter is based on a question or questions covering diverse topics such as genetic and biological origins of handedness, familial and hormonal influences on handedness, and the effects of a majority right-handed world on the behaviors of left-handers. Summarizes scientific research on laterality Separates fact from fiction in common beliefs about laterality Includes illustrative interviews with left-handers
